To determine the result, J = A -> B -> C +> D, the vectors must be relocated tip-to-tail or tip-to-tip, depending on whether they are added or subtracted. Vector B must be drawn pointing toward vector A because B is being subtracted. A similar approach is taken with vector C. The tail of vector D is then placed on the tail of C because D is to be added to the series of previously assembled vectors. The completed vector diagram is shown in Figure 3.25.
